After Lin Feng returned to the dormitory, he went headlong into the small training room in the dormitory. Bai Yu looked at Lin Feng who hurriedly entered, and didn't know what he wanted to do.

Lin Feng sat cross-legged on the futon in the training room, took out the "Medicine God Treasure Book" from the space ring and looked at it carefully, as if he was looking for something.

After an hour, he finally stopped when he turned the page, and looked at it with golden eyes.

What is recorded on that page is a pill called "Demon Yuan Dan", which is a pill specially prepared for magicians, and ordinary martial artists will not have much effect after taking it.

After the magician takes it, it can not only enhance the strength of the magic, but also greatly increase the magic power, which is a treasure that many magicians dream of.

Lin Feng laughed, he finally found it, if he refined a "Demon Yuan Dan" and gave it to Senior Sister Yunqin, she would definitely like it.

After taking a closer look at the refining method, it is basically the same as the refining method of other pills, but the failure rate of this elixir to increase mana is very high, and the alchemist needs to have a high alchemy method, and the control of the heat must be perfect to ensure the success rate.

Lin Feng took a closer look at the elixirs he needed, and he needed a total of seven or eight elixirs.

Lin Feng looked at the appearance of the elixir recorded above, remembering that when he was in Butterfly Valley before, he had picked several of these elixirs, and looked at them from the spatial ring again.

After a while, he opened all the elixirs in those jade boxes, and found the three elixirs he needed in them, but the remaining four elixirs, Lin Feng had indeed never seen or heard of them.

For a while, I didn't know where to look for it, so I carefully wrote down the name and appearance of the elixir I needed, and hurriedly walked out.

He vaguely remembered that there was a chamber of commerce on the street outside the academy. When they went to the restaurant to drink before, they met once when they passed by there.

After saying hello to Bai Yu, he hurriedly walked out in the direction of the gate of the academy.

As soon as he walked to the gate of the academy, he saw Elder Feng, and Elder Feng naturally saw Lin Feng who was walking in a hurry, and asked, "Boy Lin Feng, why are you going, in such a hurry?"

Lin Feng and Elder Feng were very familiar with each other, and there was nothing to avoid, so he explained to Elder Feng that he was going out to buy magic elixirs.

After hearing this, Elder Feng asked, "Why are you kid buying so many magic elixirs, and you don't know how to do alchemy, could it be you?"

Lin Feng laughed and said, "Hehe, I know a little bit about it, and the student only knows a little bit about the skin, refining some simple pills." ”

Hearing the name of the elixir that Lin Feng had just said, Elder Feng had roughly guessed that Lin Feng was going to refine the "Demon Yuan Pill".

Although he was a martial artist, he had also heard a little about this famous "Demon Yuan Dan" that could enhance the magic power of magicians, and he also knew what elixirs were roughly needed, so as soon as Lin Feng said the name of the elixir, he probably guessed that it was "Demon Yuan Dan".

This elixir is not something that an entry-level alchemist can refine, and at least it needs a fourth-grade flame or even a higher-grade flame, as well as the control of the fire.

This kid is really hidden, it seems that his hole cards are more than these, he has to report to the academy, then Elder Feng thought to himself.

Then he said to Lin Feng: "You kid, I think my old man doesn't know anything, the elixir you need is obviously the Demon Yuan Pill, and being able to refine the elixir is not a secret that can't be said, what's the matter, even I, the old man, are hiding it." ”

Lin Feng smiled and scratched his head, he was indeed a little embarrassed about what Elder Feng said, Elder Feng was usually very good to him, so he shouldn't hide it from him.

After thinking about it, Lin Feng said to Elder Feng: "Elder Feng, I'm sorry, the student shouldn't hide it from your old man, it's not that I'm afraid that there will be more people who know and bring unnecessary trouble to myself, so I didn't say it, don't mind your old man." ”

Elder Feng also knew that Lin Feng was afraid that someone would pay attention to him, so he didn't say anything, and he didn't care too much, after all, it was understandable.

Immediately after, Elder Feng took out a jade box from the space ring and handed it to Lin Feng, saying, "You can take this, you can use it, it's useless to keep it here with me." ”

Lin Feng took the jade box and opened it to see that it was a five-hundred-year-old elixir, which was the most precious elixir he needed to refine the "Demon Yuan Pill".

I was worried that I wouldn't be able to find this elixir before, but I didn't expect Elder Feng to give him a plant, which was still five hundred years old, and he was overjoyed.

Hurriedly thanked Elder Feng, Elder Feng didn't take this elixir seriously, so Lin Feng didn't have to be polite.

After all, for him, a respected elder, this elixir was nothing, but for Lin Feng, it was simply a send-off, without this elixir, it was likely that there would be no way to refine the "Demon Yuan Pill", so Lin Feng insisted on thanking him.

Elder Feng couldn't resist Lin Feng, so he promised to let Lin Feng refine an elixir for him in the future in return, and Lin Feng was relieved, otherwise it would not be good to always owe Elder Feng a favor.

Putting away the jade box, Lin Feng walked straight towards the commercial street, came to the chamber of commerce that he was passing by, and stood at the door and stopped.

The door of the Chamber of Commerce is very wide, and above the wide doorway, there is a huge plaque, and the huge plaque has several big characters written on it, "Heavenly Spirit Medicine Hall".

Lin Feng's first feeling was that this chamber of commerce was not simple, and the words "Heavenly Spirit Medicine Hall" alone were not written by ordinary people. You can feel the unrestrained domineering spirit from it, which should have been written by a sword master.

The whole "Heavenly Spirit Medicine Hall" looks particularly quaint, and it is particularly unique in the entire bustling commercial street.

It is like a lotus character that is out of the mud but not stained, and the lotus character is clear and rippling but not demonic, revealing a sense of vicissitudes.

Lin Feng walked straight in, and a middle-aged man in his forties at the front desk saw Lin Feng walking in, and hurriedly said, "Hello, guest officer, what kind of elixir do you want? ”

Lin Feng took out a piece of paper, handed it to the middle-aged man, and said, "If you want these elixirs, I don't know if you have them here?" ”

The man took the piece of paper with the name of the elixir, glanced at it and said, "Yes, yes, you wait, I'll prepare." Then he went into the house and went to prepare the elixir.

Lin Feng was not in a hurry, sitting on a stool in the hall, observing the situation in the hall.

This hall, like the outside, looks particularly quaint, and the whole hall has no furniture except for medicine shelves, a front desk and some stools, and it looks empty.

On both sides of the hall stand two pillars, which are the pillars of the store, supporting the beams above.

Lin Feng looked around the two pillars curiously, and when he came in just now, he was in a hurry and didn't take a closer look. A closer look reveals that there are words on these two pillars.

One pillar reads "I wish there was no suffering in the world" and the other said "I'd rather put medicine on the shelf to produce dust", and when I looked up, there was a smaller plaque on the beam between the two pillars, which said "Save the world and help people".

Lin Feng looked at these words carefully, and the handwriting on the plaque outside was exactly the same, it should have been written by the same person, this "Heavenly Spirit Medicine Hall" is indeed not simple.

Lin Feng stretched out his fingers and touched the handwriting, feeling the momentum contained in them. These words seemed to come to life, and the sword intent deeply touched Lin Feng's heart.

At this time, the middle-aged man walked out from behind, saw Lin Feng touching the two pillars, and hurriedly said, "Don't touch it, let it go." ”

Hearing the middle-aged man say this, Lin Feng reluctantly cut off the feeling just now, and quickly let go of the pillar.

Seeing that he was already sweating profusely, he couldn't help but be shocked and asked, "What is the situation? How can I sweat? I still feel just now." ”

The middle-aged man hurriedly walked over and investigated Lin Feng, and he was relieved after nothing serious.

Hurriedly said: "The guest officer doesn't know, these handwritings are written by a sword saint predecessor with sword intent, and the incomparable sword intent contained in them will hurt the state of mind of a martial artist with a lower cultivation level and make him go mad." ”

After listening to the middle-aged man's words, Lin Feng shuddered with fright, fortunately he was stopped in time just now, otherwise he didn't know what would have happened.

However, Lin Feng was very interested in this sword saint who wrote with sword intent, and hurriedly asked: "Senior can you introduce this sword saint senior in the next step, I am also a swordsman, I am particularly interested." ”

The man in the middle did not shy away from it, and began to introduce Lin Feng, and only stopped talking for an hour. It also allowed Lin Feng to know and understand the story of this Sword Saint predecessor and the origin of this "Heavenly Spirit Medicine Hall".

It turns out that this Sword Saint predecessor is called "Heavenly Spirit Sword Saint", who lived five thousand years ago and was once the dean of the Kamikaze Academy, a very good swordsman, and also a very good alchemist.

He once traveled to various empires and regions in the Zhongzhou Continent, challenging major masters, and collecting all kinds of elixirs along the way.

Since it was difficult to meet opponents in the entire continent at that time, there was nothing too dangerous in the continent for him, so it was particularly easy to collect.

At that time, the "Heavenly Spirit Sword Saint" set off a bloody storm in the entire continent with his superb swordsmanship, defeated many famous sword saints at that time, and won the title of "First Sword Saint" in the Zhongzhou Continent.

However, this also made him a thorn in the side of many Sword Saint families, who wanted to join forces to get rid of him. Because if you don't get rid of him, you will be challenged by him, and if you lose, it will be very embarrassing for the family.

Therefore, many unconvinced Sword Saints and Sword Masters who have not yet been challenged have formed a temporary Sword Saint Alliance, ready to intercept and kill the "Heavenly Spirit Sword Saint".

When the "Heavenly Spirit Sword Saint" challenged the next opponent, these Sword Saints joined forces to suddenly attack, seriously injured the "Heavenly Spirit Sword Saint", and cut off the right arm holding the sword.

But fortunately, at that time, under the siege and interception of these sword saints, the "Heavenly Spirit Sword Saint" miraculously escaped, and traveled all the way, evading the pursuit and returning to the kamikaze school.

However, because his right arm was cut off, the "Heavenly Spirit Sword Saint" felt very humiliated, so he stepped down from his position as the dean of the Kamikaze Academy, and built a small building outside of this academy to live in.

At that time, the "Heavenly Spirit Sword Saint" was so high-spirited and powerful, but in the end, he still ended up with his right arm cut off and fled in a hurry.

Later, because the "Heavenly Spirit Sword Saint" realized that the true meaning of a martial artist is his own state of mind and the realm of cultivation, the final outcome should be to ascend to the divine realm instead of fighting fiercely.

After realizing this, the state of mind of the "Heavenly Spirit Sword Saint" changed greatly, and he was no longer fighting with others. Instead, he closed the door and did not see the guests, recreated a set of left-handed swordsmanship, and restored it to the realm of its peak.

But at this time, he no longer had the heart to fight, so he relied on his excellent alchemy technique to open this "Heavenly Spirit Medicine Hall".

After that, the "Heavenly Spirit Sword Saint" often went out to parade, save the dead and help the wounded, pick all kinds of elixirs, and refine all kinds of elixirs. For a while, the name of "Heavenly Spirit Sword Saint" was even louder than before.

The "Heavenly Spirit Sword Saint" also knows that reputation does not necessarily have to be achieved by defeating others, but if you do good deeds and your strength reaches a certain level, you will naturally be respected by others.

He returned to the "Heavenly Spirit Medicine Hall" and settled down here, and wrote two plaques with a sword in the "Heavenly Spirit Medicine Hall", which were the big plaque on the outside that Lin Feng saw and the small plaque on the inside to save the world.

Since the reputation of the "Heavenly Spirit Sword Saint" had already been played before, people often came to visit and ask for medicine. Slowly, the reputation of the "Heavenly Spirit Medicine Hall" is getting louder and louder.

When the "Heavenly Spirit Sword Saint" was saving the world in various ways, he also encountered some warriors and patients who could not be cured, and watched these people die in front of his eyes.

Deeply feeling the suffering of the world, he wrote on these two pillars: "I hope that there is no suffering in the world, and I would rather put medicine on the dust." "It has been highly recognized by everyone.

Later, the "Heavenly Spirit Sword Saint" disappeared, leaving this "Heavenly Spirit Medicine Hall" to an apprentice he had accepted at that time, and it was said that he had ascended to the Divine Domain.

Although Lin Feng had never met this "Heavenly Spirit Sword Saint", listening to his story, he was completely attracted by him, and his heart was full of respect.

No wonder he was attracted by this handwriting full of sword intent, because the sword intent is the same.

Then Lin Feng chatted with the middle-aged man for a while, took the elixir, paid the money, and left here and returned to the training room of his dormitory in the academy.

In the space ring, he took out the Ten Thousand Beasts Ding, put it on the ground, put the required elixirs next to him one by one, and took out the jade knife to divide these elixirs into three parts.

After everything was ready, Lin Feng looked at the pill again and confirmed that it was correct before starting to refine the pill.

Lin Feng summoned the "Origin Fire" from the sea of knowledge and started the furnace, and after a while, the Dan furnace was warmed up. Immediately after that, the required elixirs were put in one by one in order and covered with a lid.

This was Lin Feng's first time refining the "Demon Yuan Dan", so he was extremely cautious, for fear that something would go wrong, on the one hand, he strictly controlled the fire, and on the other hand, he released his divine sense to investigate, and his divine sense never left the Dan furnace during the whole process.

The various elixirs in the Dan Furnace continued to melt with the passage of time, and Lin Feng used his divine sense to gather these melted elixirs into the shape of the elixir.

Looking at the formed elixir, Lin Feng became more cautious, sweating on his forehead, carefully controlling the heat, not daring to be careless.

Half an hour later, a "snort" came out of the Dan furnace, and Lin Feng knew that the pill had been completed, and the next step was to open the furnace.

Lin Feng put away the Origin Fire and shouted: "Fire extinguishing furnace open" and quickly lifted the lid.

quickly looked at the Dan furnace, and a elf-clear elixir in the Dan furnace lay quietly in the middle.

Lin Feng picked up this pill and put it in the palm of his hand, a bright smile leaked from the corner of his mouth, it was successful, the first refining was successful.

I have to say that Lin Feng's luck is very good, of course, his five-rank origin fire and simple skills are also undeniable.

Looking at this quail egg-sized "Demon Yuan Dan" Lin Feng took out a jade box from the space ring, put it in, and placed it properly.

Then I packed up these things, and went back to sleep with a good heart, it was already late at night, and I could sleep for a while.

The next time I see Senior Sister Yunqin, she will definitely be happy if she gives her this "Demon Yuan Dan". Hahaha.
